SHARPENING DEVICE.

Application filed October '17, 1925. Serial No. 63,070.

This invention relates to an improved device, particularly adapted forsharpening knives, scissors, and the like, the same having particularreference to a device of this kind which is constructed to permit it tobe supported on a kitchen table, shelf or the like, so that it may bereadily accessible and conveniently used from time to time to keep theknives in good order.

My principal object is to generally improve upon inventions of this kindby provid ng one of comparative simplicity and durability, which may bereadily placed in position for use, one which is convenient and easy tomanipulate, and which is such in constructionas to permit it to bemanufactured and sold at a minimum cost.

Other objects and advantages of the invention will become apparent fromthe fol lowing description and drawing.

In the accompanying drawing forming a part of this application, and inwhioh like numerals are employed to deslgnate like parts throughout thesame:

Figure 1 is an elevational view of a knife sharpening device constructedin accordance with the present invention.

Figure 2 is a side view of the same showing the approximate manner ofmounting the device upon a table top or similar support.

In carrying out the inventionl provide a single metal strip, the samebeing adapted for vertical disposition as shown in the drawing and beingbifurcated at its top to pro vide a pair of outwardly diverging guidefingers 1. These fingers are substantially duplicate in design and havetheir inner opposed edges bowed longitudinally as shown plainly inFigure 1. These fingers are of a size to serve as effective mountingsfor a pair of rotary sharpening discs 2. It is understood, of course,that these discs are not in any sense freely rotatable, but as they wearfrom constant use, the constant pressure of the knife blade thereonturns them with respect to each other to bring into playnew and unwornsharpening surfaces.

The strip of metal referred to is bent to form novel means for mountingthe device upon a table, or the like, 3. More specifically, the strip isbent as at 4 below the sharpening means, being directed at aright'angle, bent upon itself as at 5, and then down at a right angle asat 6, thus forming a clamping jaw 7. The lower end of the strip is bentinwardly on a horizontal line as at 8 to provide the lower complementaljaw. Through this part 8 a thumb screw 9 is threaded, and a swiveledhead is carried by the inner end of this screw and is adapted toengagethe bottom of the table as shown in Figure 2. In this way thedevice may be firmly clamped on a table, shelf, or other equivalentsupport, after which the knife blade will be placed between theperipheral edges of the two discs and drawnback and forth to put a sharpcutting edge upon the same.

From the foregoing description and drawing it is obvious that I haveevolved and produced a simple and inexpensive device for sharpeningscissors and knivesin an efficient manner. The construction is quitesimple as it is believed that by considering the description inconnection with the drawings, a clear comprehension of the inventionwill be had. Therefore, a more lengthy description is deemedunnecessary. While the preferred embodiment of the invention has beenshown and described it is to be understood that minor changes comingwithin the field of invention claimed may be resorted to if desired. V

l-Iaving thus described the invention, what I claim as new is As a newarticle of manufacture, a, sharpening device for knives, scissors andsimilar articles comprising a stamped metal strip provided at one endwith a pair of outwardly diverging guide fingers, said fingers beinggradually decreased in width from their innor toward their outer endsand having curved edges opposed to each other, the intermediate portionof said strip being bent at right angles to the body portion, beingreturned to provide superposed plies forming a clamping jaw, the lowerend portion of the strip being bent downwardly to extend in alignmentwith the aw carrying portion, and

terminating in a laterally bent end disposed in parallelism with saidfirst named jaw, a pair of turnable sharpening discs mounted forrotation upon the intermediate portions of the fingers at pointsopposite each other with their peripheral edges in abutting relation,and a clamping screw carried by the laterally bent lower ends of saidmetal strips.

In testimony whereof I afliX my signature.
